1 = Force 34 transmit pattern
0 = Normal operation
1 = 100BASE-TX link good
0 = Normal operation
This bit is reserved and should be set to 0b.
1 = Transmit Carrier Sense disabled
0 = Transmit Carrier Sense enabled
1 = Dynamic Power-Down disabled
0 = Dynamic Power-Down enabled (normal)
1 = Auto-Negotiation loopback
0 = Auto-Negotiation normal mode
1 = MDI Tri-state (transmit driver tri-states)
0 = Normal operation
1 = By-pass filter
0 = Normal filter operation
1 = Auto Polarity disabled
0 = Normal polarity operation
1 = 10BASE-T squelch test disable
0 = Normal squelch operation
1 = 10BASE-T Extended Squelch control enabled
0 = 10BASE-T Extended Squelch control disabled
1 = Link disabled
0 = Normal Link Integrity operation
1 = Jabber disabled
0 = Normal Jabber operation
These bits are reserved and should be set to a
constant ‘0’
These bits are set to the PHY’s address, 00001b.
These bits are used for the false carrier counter.
